Detailed implementation manners

[0034] Embodiment 1

[0035] As Figures 1 - 5 shown, a bending die for safe processing includes a base 1. Both ends inside the base 1 are installed with side plates 2 through screws. A plurality of return springs 3 are arranged between the two side plates 2 inside the base 1. The tops of the plurality of return springs 3 are connected by a lower die 4. The lower die 4 is slidably connected inside the base 1. The top of the base 1 is connected with an electro-hydraulic rod 5 through a connecting frame. The bottom of the electro-hydraulic rod 5 is installed with an upper die 6 through screws. It is characterized in that: a bending auxiliary part 7 is arranged at the top end of the base 1. The bending auxiliary part 7 includes a connecting rod 701, a positioning part 702, an adjusting part 703, a dust removing part 704, an extrusion limit assembly 705 and a stripping part 706;

[0036] One end of the upper die 6 is installed with a connecting rod 701 through a screw. One end of the top of the base 1 is installed with a positioning member 702. The positioning member 702 realizes position adjustment through an adjusting member 703. A dust removing member 704 is installed at the end of the base 1. An extrusion limiting assembly 705 is installed on the top of the lower die 4, and an extrusion limiting assembly 705 is arranged at the bottom of the lower die 4.

[0037] Place the workpiece on the top surface of the lower die 4, turn on the electric hydraulic rod 5, drive the upper die 6 to move, and realize the pressing of the part through the movement of the upper die 6. Along with the pressing process of the part, and through the shape matching of the upper die 6 and the lower die 4, the bending process of the part is realized. During the bending process of the part, the dust inside the lower die 4 can be removed and the two ends of the lower die 4 can be clamped and limited, making the bending effect of the part better. At the same time, the demoulding of the part can be realized after the part is bent.

[0038] The positioning member 702 includes a bidirectional threaded rod 7021, a limiting block 7022, a driving gear 7023 and a driving rack 7024;

[0039] One end of the top of the lower die 4 is provided with a bidirectional threaded rod 7021. Both ends of the outer side of the bidirectional threaded rod 7021 are connected with a limiting block 7022 through threads. The cross section of the limiting block 7022 is L-shaped, which is convenient for limiting the end of the part. One end of the bidirectional threaded rod 7021 is fixedly connected with a driving gear 7023. One end of the bottom of the connecting rod 701 is provided with a driving rack 7024. The bottom surface of the limiting block 7022 is in contact with the top surface of the lower die 4, and the driving rack 7024 is meshed with the driving gear 7023;

[0040] When the electric hydraulic rod 5 pushes the upper die 6 to move, it drives the connecting rod 701 to move. Through the movement of the connecting rod 701, the driving rack 7024 is driven to move. Through the meshing connection between the driving rack 7024 and the driving gear 7023, the driving gear 7023 is driven to rotate. Through the rotation of the driving gear 7023, the bidirectional threaded rod 7021 is rotated. Through the rotation of the bidirectional threaded rod 7021, the limiting block 7022 is moved, so that the limiting block 7022 does not contact the end of the part, which is convenient for the subsequent bending process of the part, and avoids the problem that the limiting block 7022 blocks the end of the part during the bending process of the part and affects the bending of the part. When the driving rack 7024 is not in contact with the driving gear 7023, the position of the limiting block 7022 remains unchanged at this time. After the bending of the part is completed, when the upper die 6 moves upward, the driving rack 7024 is meshed with the driving gear 7023 again, and the driving gear 7023 is driven to rotate in the reverse direction, so that the limiting block 7022 is reset, and the end of the next part is limited, which is convenient for the bending process of the next part, without manual adjustment of the part position by personnel, reducing the labor intensity of personnel, and at the same time improving the accuracy of part bending.

[0041] The adjusting member 703 includes an adjusting screw rod 7031, an adjusting block 7032, and a manual adjusting rod 7033;

[0042] One end of the lower die 4 is rotatably connected to the adjusting screw rod 7031. The adjusting block 7032 is threadedly connected to the outside of the adjusting screw rod 7031. The bidirectional threaded rod 7021 is rotatably connected to one end of the adjusting block 7032. The driving rack 7024 and the connecting rod 701 are connected by the manual adjusting rod 7033. The adjusting block 7032 is slidably connected to the inside of the lower die 4 to ensure the stability of the movement of the adjusting block 7032, thereby realizing the stability of the movement of the bidirectional threaded rod 7021;

[0043] The operator can adjust the position of the adjusting block 7032 by rotating the adjusting screw rod 7031, and then adjust the position of the bidirectional threaded rod 7021. The position of the bidirectional threaded rod 7021 is adjusted according to parts of different lengths, which is suitable for bending parts of different lengths. After moving the bidirectional threaded rod 7021 to a suitable position, the operator can make the driving gear 7023 and the driving rack 7024 meshed by adjusting the manual adjusting rod 7033. When bending parts of different widths, when the operator makes the driving gear 7023 not meshed with the driving rack 7024, the operator can adjust the position of the limiting block 7022 by rotating the bidirectional threaded rod 7021. After adjusting the limiting block 7022 to a suitable position, the driving gear 7023 and the driving rack 7024 can be meshed. The position of the limiting block 7022 can be manually adjusted, which is convenient for limiting parts of different widths and lengths and bending parts of different lengths and widths.

[0044] The dust removing member 704 includes a pressing rod 7041, a pushing plate 7042, a fixed box 7043, a gas one-way valve 7044, an air outlet pipe 7045, a collecting box 7046, and a dust inlet pipe 7047;

[0045] One end of the base 1 is installed with the fixed box 7043 by screws, the other end of the base 1 is installed with the collecting box 7046 by screws. One end of the bottom of the connecting rod 701 is installed with the pressing rod 7041 by screws, the pressing rod 7041 is installed with the pushing plate 7042 by screws at the bottom. The pushing plate 7042 is slidably connected to the inside of the fixed box 7043. Both ends of the bottom of the fixed box 7043 are fixedly connected with the gas one-way valves 7044. One end of a gas one-way valve 7044 is fixedly connected with the air outlet pipe 7045. The air outlet pipe 7045 is fixedly installed at one end of the middle part of the lower die 4. One end of the top of the collecting box 7046 is fixedly connected with the dust inlet pipe 7047. One end of the dust inlet pipe 7047 is fixedly installed at the other end of the middle part of the lower die 4.

[0046] The intake directions of the two gas one-way valves 7044 are opposite. The end of the dust inlet pipe 7047 close to one end of the lower die 4 is conical, which is convenient for collecting and processing impurities, and is also convenient for extruding the inside of the fixed box 7043 and blowing air to the impurities.

[0047] When bending the part, when the connecting rod 701 moves downward, the moving connecting rod 701 drives the pressing rod 7041 and the pushing plate 7042 to move, realizing the movement of the pushing plate 7042 inside the fixed box 7043. The gas at the bottom inside the fixed box 7043 passes through the gas one-way valve 7044 and then is ejected through the air outlet pipe 7045 to clean the inside of the lower die 4. The cleaned impurities enter the dust inlet pipe 7047 and then enter the inside of the collection box 7046 for collecting and processing the impurities. During the impurity cleaning process, since there are parts blocking the top surface of the lower die 4 and the lower die 4 is inside the base 1, the problem of impurities splashing will not occur at this time, ensuring the collection and processing of impurities. The inside of the lower die 4 can be cleaned of impurities, avoiding the problem that the impurities accumulated inside the lower die 4 during the bending process of the previous part affect the bending of the current part, and ensuring the accuracy of part bending.

[0048] Embodiment 2

[0049] On the basis of Embodiment 1, as Figure 2 、 Figures 6 - 8 shown, the extrusion limiting component 705 includes a rotating shaft 7051, a bevel gear connection mechanism 7052, a threaded barrel 7053, a pushing screw 7054, a pushing rod 7055, a spiral spring 7056, a limiting plate 7057, a driving gear 7058 and a fixed toothed bar 7059;

[0050] One end inside the lower die 4 is rotatably connected with a rotating shaft 7051. Two bevel gear connection mechanisms 7052 are arranged on the outer side of the rotating shaft 7051. The top of the bevel gear connection mechanism 7052 is fixedly connected with a threaded barrel 7053. The threaded barrel 7053 is rotatably connected inside the lower die 4. A pushing screw 7054 is connected inside the threaded barrel 7053 through a thread. The top of the pushing screw 7054 is fixedly connected with a pushing rod 7055. Spiral springs 7056 are arranged at both ends of the top of the lower die 4. One end of the spiral spring 7056 is fixedly connected with a limiting plate 7057. One end of the rotating shaft 7051 is fixedly connected with a driving gear 7058. One end of the base 1 is installed with a fixed toothed bar 7059 through a screw. The fixed toothed bar 7059 is meshed and connected with the driving gear 7058.

[0051] Arc angles are formed at both ends of the top of the pushing rod 7055. The pushing rod 7055 is located at the bottom of the limiting plate 7057. The pushing rod 7055 is slidably connected inside the lower die 4, ensuring the stability of the movement of the pushing rod 7055 and enabling the rotation of the limiting plate 7057 through the movement of the pushing rod 7055.

[0052] The bevel gear connection mechanism 7052 includes two bevel gears which are meshed and connected. One bevel gear is fixedly sleeved outside the rotating shaft 7051, and the other is fixedly installed at the bottom of the threaded barrel 7053. The rotation of the rotating shaft 7051 can drive the rotation of the threaded barrel 7053 to realize the movement of the push rod 7055.

[0053] As the part is bent, the movement of the upper die 6 will push the part and the lower die 4 to move, causing the return spring 3 to be compressed. The movement of the lower die 4 drives the driving gear 7058, making the driving gear 7058 meshed and connected with the fixed tooth bar 7059. Since the position of the fixed tooth bar 7059 is fixed, the driving gear 7058 will rotate at this time, driving the rotation of the rotating shaft 7051. Through the connection of the bevel gear connection mechanism 7052, the rotation of the threaded barrel 7053 is driven. Through the threaded connection between the threaded barrel 7053 and the push screw 7054, the push screw 7054 can be driven to move, realizing the movement of the push rod 7055. By the movement of the push rod 7055, the limiting plate 7057 is pushed to rotate, so that the two ends are respectively in contact with the ends of the two limiting plates 7057, and then the limiting plates 7057 are in contact with the bent ends, ensuring the accuracy of the part bending. Avoiding the problem of poor bending accuracy caused by deformation at both ends during the bending process of the part. And through the pressure on both ends of the part, it can help the two ends of the part to be quickly formed, accelerating the bending efficiency. The fixed tooth bar 7059 can be adjusted according to the length of the part. After the bending of the part is completed and the upper die 6 is reset, the spiral spring 7056 makes the limiting plate 7057 reset, facilitating the bending process of the next part.

[0054] Embodiment Three

[0055] On the basis of Embodiment One or Two, as Figure 2 、 Figure 9 and Figure 10 shown, the demolding part 706 includes a driving rod 7061, a fixed spring 7062, a driving plate 7063 and a demolding plate 7064;

[0056] Both ends of the bottom of the connecting rod 701 are installed with driving rods 7061 through screws. The bottom end inside the lower die 4 is fixedly connected with a fixed spring 7062. The bottom of the fixed spring 7062 is welded with a driving plate 7063. The top of the driving plate 7063 is installed with a demolding plate 7064 through screws. The demolding plate 7064 is slidably connected inside the lower die 4, facilitating the demolding of the bent part. The driving rod 7061 is at the bottom of the driving plate 7063, facilitating the movement of the driving plate 7063.

[0057] When bending the part, the connecting rod 701 moves downward to drive the driving rod 7061 to move. At this time, the fixing spring 7062 resets and pushes the driving plate 7063 to move, moving the stripping template 7064 to the bottommost position inside the lower die 4. At this time, the driving rod 7061 does not contact the driving plate 7063, realizing the bending process of the part and avoiding the stripping template 7064 blocking the bending operation of the part. After the part bending is completed, the connecting rod 701 moves upward to drive the driving rod 7061 to move, making the driving rod 7061 contact the driving plate 7063 and pushing the driving plate 7063 to move, thereby driving the stripping template 7064 to move. The bent part is driven to move by the movement of the stripping template 7064, so that the part is removed from the inside of the lower die 4, facilitating the operator to take the bent part and avoiding the problem that the bent part is stuck inside the lower die 4, which makes it inconvenient for the operator to take it, thereby improving the efficiency of part bending.

[0058] Place the workpiece on the top surface of the lower die 4, turn on the electro-hydraulic rod 5 to drive the upper die 6 to move, and press the part by the movement of the upper die 6. When the upper die 6 moves, it drives the connecting rod 701 to move. The driving rack 7024 is driven to move through the movement of the connecting rod 701, realizing the rotation of the driving gear 7023 and the bidirectional threaded rod 7021, so that the limiting block 7022 does not contact the part. As the upper die 6 moves downward, at this time, the impurities inside the lower die 4 are processed by the dust removal part 704, avoiding the problem that the accumulation of impurities inside the lower die 4 affects the bending accuracy of the part. Since the lower die 4 is connected to the reset spring 3, when the upper die 6 first bends the part to a certain angle, when the downward pressure of the electro-hydraulic rod 5 is greater than the elastic force of the reset spring 3, the upper die 6 will drive the lower die 4 and the part to move, compressing the reset spring 3. When the lower die 4 moves, it will gradually bend the part. When the bottom surface of the lower die 4 moves to contact the top surface of the side plate 2, the movement of the lower die 4 stops, while the upper die 6 is still moving downward until the part bending is completed. When the lower die 4 moves, it drives the extrusion limiting component 705 to operate, making the limiting plate 7057 rotate to limit the two ends of the part, and pressure can be applied to the two ends of the part during the bending process, facilitating the rapid forming of the part and accelerating the part bending efficiency. After the bending is completed, the upper die 6 moves upward, making the connecting rod 701 move upward, and then driving the driving rod 7061 to move, finally realizing the movement of the stripping template 7064 and the demoulding of the bent part. With the pressing process of the part and the shape matching of the upper die 6 and the lower die 4, the part bending process is realized. During the part bending process, the dust cleaning inside the lower die 4 and the clamping and limiting of the two ends of the lower die 4 can be realized, making the part bending effect better. At the same time, after the part bending, the demoulding of the part can be realized. After the upper die 6 moves to the original position, the limiting block 7022 and the pushing plate 7042 also reset, facilitating the next part bending process.
